• Direct thermal
• 40 × 20 mm
• 2,000 labels
• 1.5" core

BlackCopper BC-DTL-40x20-2up is a roll of 2,000 bright white 40 × 20 mm direct thermal barcode labels, two across on a 1.5" core — 1,000 rows of 2.

The 40 × 20 mm format is the everyday retail barcode label: big enough for a scannable EAN or SKU barcode with a short text line, small enough to sit on almost any product. Two labels run side by side across the liner, so the printer produces two labels in each pass and a long job finishes in half the length of roll. The 1.5" (38 mm) core fits standard desktop label printers. Direct thermal labels carry a heat-sensitive coating that turns black under the print head, so there is no ribbon to buy, load or change. That keeps running costs low and setup simple, and suits labels with a short working life. Keep printed labels away from heat and strong sunlight, which darken the coating over time.
